Moise Pinion, or sfr. JEAN PORTJOLI, QUEBEC, CANADA, ASSIGNOR 'I THE CANADIAN BAILW'AY GATE MANUFACTURNG CMPANY, OF ST. JEAN .PORT- J" OLI, QUEBEC, CANADA.

To all whom t may concern v Be it known that LlMorsn FILION, a citiren of the Dominion of Canada, and resident of St. Jean Port-Joli, in the Province of Quebec and Dominion Vof Canada, have invented new and useful improvements in Cattle-Guards, of which the following is a full, clear, and exact description.

This invention relates to improvements in cattleguards, and the object is to provide a strong and durable guard which in its normal Vposition leaves the railway line open for the passage of trains, but operates automatically to block the railway line when a person or animal attempts to pass from the railway crossing on to the railway line.

A 'further' object is to provide a guard which if it should stick in'elevated position the device. Fig. 2 is a sectional'view showing the method of mounting the barrier shaft. Fig. 8 is a sectional view on the line 3&8, Fig. 1l. Fig. 4 is a perspective view of oneof the barrier members. Fig. 5 is a per# spective View of the operating spring. Fig. Gis a perspective View of one of the platforml elevating springs. Referring more particularly to the drawings, 11 designates the rails of a track which, adjacent the guard, are mounted on string-v ers 12carried on sunken ties 18. These ties are longer than usual so as to project a considerable distance beyond the track at each side and forma foundation for the guard, and permit all working parts to be inserted below the rail base.

At each side of the railway crossing 14, platforms or tread plates 15 are provided between and on each side of the rails, and

are pivoted at the ends adjacent the crossing-` Speccation of Letters Patent.

CATTLE-GUARD.

on a transverse shaft 16, the opposite end being left free. A suitable distance beyond the free ends of the plates 15, transverse shafts 17 are provided carrying rigidly mounted guards or barriers composed preferably of bars 18. These bars may be ofany suitable material, butit is preferred to make same of angle section. The section -of the with the angles doubled at the sides and center as shown, and the side sections of the barrier formed with only the. angles adj acent the rails doubled or in any other suitable way. The ends of these angles are connectedat the ends mounted on the shaft by transverse members 19, and again intermediate their ends by transversemembers 20. Diagonal braces 21 are also provided to carrier between the rails may be formed stiifen the structure. Adjacent the` sides of each section, short intermediate bars 22 are provided extending between the transverse members 19 and 20, Suitably shaped links 23 are pivoted between the bars 22 and adjacent bars 18, and extend beyond the shaft 17 slightly under the free ends of the tread plates 15, to which they areconnected by suitably shaped links 24 pivoted to ears 25 mounted on the undersides of the plates. It

will thus be seen that each section of the barrier is independently connected to the adjacent tread plate. If the shaft 17 is continuous `from one side of the barrier to the other, any of the tread plates will operate all three sections of the barrier .on the' same side of `the crossing `as itself, but if the shaft 17 is divided according to the number of sections in the barrier each tread platev will operate only the adjacent section of barrier.

rlhishfeature may be arranged as circumstances require. The center arm of the center barrier section is provided with a pair of arms 26 and 26a extending on the opposite side 'of the shaft from the arm and arranged at an angle of approximately CJ to one another. The arm 26 isconnected by a chain 27 with one member 28 of a spring carrier. rlhe other member 29 of the spring carrier is pivotally connected to the shaft 16 or to other suitable anchorage, and is slidably arranged with respect to the member-28. Each l of these members is provided with an enlarged head 30, the headsholding between them a helical spring 81. The arm 26a is i ber 32.

-Tread plate cushions or elevators 33 are secured to one of the cross ties under the free corners of the tread plates. The purpose of these is to insure the rise of the platform as soon as a person or animal steps off` the same, so that the weight of the platforms and the lifting of same is not thrown entirely on the barrier operating spring 31. These elevators each consist of a framework 34 bolted or spiked to the tie, and containing a suitably mounted helical spring 35 .which is normally just clear of the tread plate when the same is in elevated position.

The operation of the device is extremely simple. In normal position, the parts are as shown in full lin, Fig. 3. When sufficient downward pressure is exerted 1 on the tread plates 15, as for example, by a person or animal stepping from the crossing 14 on to them, one of the tread plates is depressed to horizontal position, and acting through the links 24' and 23 'raises the barrier to the vertical position shown in dotted Y lines, the link 23 being fulcrumed across theshaft 17 and acting asa leveror exten- Vsionof'the barrier. When the .barrier rises to vertical position', the lever arm 26 on the central section thereof pulls Von the chain and 'moves the members of the spring carrier, so that the heads 30 approach one another and compress the spring 31. The

` elevator springs iunder the platforms are from the tread plates the elevator springsalso' compressed. When the load is removed raisethe same to normal inclined position,

andthe expansion of the springs 31 draws vt-he barrier downto normal position.

If the barriers should become stuckV in* elevated position by accumulations of snow or the like-,or for any other reason be relevated whenra train passes the crossing,1the barrier will not be injured. If the train strikes thebarrier from the'upper side', the same will depress in the ordinary manner, but if the vtrain strikes the barrier from the under slde, the same will be depressed to the position shown in dot and; dash lines, Fig. 3,

the links 23 and'24 lmoving to the posi- A tion shown.v In this position, the chain 27 Y the chain and give the spring leverage over the -barrier to return 'the same to normal 'Y p Witnesses:` Y

will be bent over the roller 32 of the bifurcated. arm 26a, s'o` that when the .train has passed, the arm 26a will receive the pull of position. This arm also keeps the spring carrier and chain suitably depressed and clear ofthe tread plates.

Having thus described my' invention, what I claim is l. The combination with a railway track and crossing of tread plates pivoted at their ends adjacent the crossing, barriers pivoted adjacent the free endsof the tread plates, Y

links pivotally connected to the barriers,

. links pivotally connected to the treadplates and to the barrier links, a lever arm car-- ried by the barrier, a telescopic springcar-V f rier fxedly mounted at one end and connected at the other. end tothe barrier lever,

and meansfor returningthe tread plates toV rier spring. A Y Y.

2. The combination with a railway track and crossing of tread plates pivoted attheir normal position independently of thev barends 'adjacentsaid crossing, a transverse shaft adjacent the free ends of said tread plates, bars of angle section f rigidly connected at right angles toV said-shaft and forming a barrier, said bars being doubled at each side ofthe rails and midwaybetween the rails to formbars of'T section, transverse tie members connectingv the bars adjacent the shaft and intermediate the ends, diagonal braces, short barssecuredfbetween said transverse `bars adjacentthe sidesfofV the vbarrier sections, linksgpivoted between saidshort bars and adjacent long bars,`links pivoted tothe tread platesA andto :theextremities of said barrier links, `a springcon-L" i 5' nected between a fixed point and the bar- Y rier.- and arranged to maintain the sameinormally in. depressed position, and springsar` ranged to maintain the tread plates norv mally in elevated position independently of the action of the barrier springs.
